CONFIRMATION DRIVING PATTERN
(a) Connect the TOYOTA hand±held tester to the DLC3.
(b) Switch the TOYOTA hand±held tester from normal mode to check mode (See page DI±197).
(c) Start the engine and warm it up with all accessory switches OFF.
(d) Drive the vehicle at 60 ~ 120 km/h (38 ~ 75 mph) and engine speed at 1,600 ~ 3,200 rpm for 3 ~ 5 min.
HINT:
If a malfunction exists, the MIL will light up during step (4).
NOTICE:
If the conditions in this test are not strictly followed, detection of the malfunction will not be possible.
If you do not have a TOYOTA hand±held tester, turn the ignition switch OFF after performing steps
(3) and (4), then perform steps (3) and (4) again.
INSPECTION PROCEDURE
HINT:
If DTC P1130 is displayed, check Bank 1 Sensor 1 circuit.
If DTC P1150 is displayed, check Bank 2 Sensor 1 circuit.
Read frame freeze data using TOYOTA hand±held tester or OBD II scan tool. Because freeze frame
records the engine conditions when the malfunction is detected, when troubleshooting it is useful for
determining whether the vehicle was running or stopped, the engine warmed up or not, the air±fuel
ratio lean or rich, etc. at the time of the malfunction.
1 Are there any other codes (besides DTC P1130, P1150) being output?
YES Go to relevant DTC chart.
NO

DTC P1780 Park/Neutral Position Switch Malfunction
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it goes on
terminal NSW of the ECM is grounded to body ground via the starter relay, thus the terminal NSW voltage
becomes 0V. When the shift lever is in the D, 2, L or R position, the park/neutral position switch goes off,
so the voltage of ECM. Terminal NSW becomes battery voltage, the voltage of the ECM internal power
source. If the shift lever is moved from the N position to the D position, this signal is used for air±fuel ratio
correction and for idle speed control (estimated control), etc.

(c) Replace the ATF.
(1) Remove the drain plug and drain the fluid.
(2) Reinstall the drain plug securely.
(3) With the engine OFF add new fluid through the oil
filler pipe.
Fluid type: ATF D±II or DEXRON®III (DEXRON®II)
Capacity: 2.5 liters (2.6 US qts, 2.1 Imp. qts)
(4) Start the engine and shift the shift lever into all posi-
tions from P to L position and then shift into P posi-
tion.
(5) With the engine idling, check the fluid level. Add
fluid up to the COOL level on the dipstick.
(6) Check the fluid level is at the normal operating tem-
perature, 70 ± 80 °C (158 ± 176 °F), and add as
necessary.
NOTICE:
Do not overfill.
(d) Check the fluid leaks.
Check for leaks in the transaxle.
If there are leaks, it is necessary to repair or replace O±rings,
gasket, oil seals, plugs or other parts.
(e) Inspect and adjust the throttle cable.
(1) Check that the accelerator pedal is fully released.
(2) Check that the inner cable is not slack.
(3) Measure the distance between the outer cable end
and stopper on the cable.
Standard distance: 0 ± 1 mm (0 ± 0.04 in.)
If the distance is not standard, adjust the cable by the adjusting
nuts.

6. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R positions.
NOTICE:
Do the test at normal operating fluid temperature 50 ± 80 °C (122 ± 176 °F).
Do not continuously run this test for longer than 5 seconds.
To ensure safety, conduct this test in a wide, clear level area which provides good traction.
The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot depressing firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
Quickly read the stall speed at this time.
Stall speed: 2,450 ± 150 rpm
(7) Do the same test in R position.
Stall speed: 2,450 ± 150 rpm
Evaluation:
ProblemPossible cause
(a) Stall speed low in D and R positions
Engine output may be insufficient
Stator one±way clutch is operating properly
HINT: If more than 600 rpm below the specified value, the torque
converter clutch could be faulty.
(b) Stall speed high in D position
Line pressure too low
Forward clutch slipping
No.2 one±way clutch not operating properly
O/D clutch slipping
(c) Stall speed high in R position
Line pressure too low
Direct clutch slipping
1st & reverse brake slipping
O/D clutch slipping
(d) Stall speed high in D and R positions
Line pressure too low
Improper fluid level
O/D one±way clutch not operating properly

(b) Measure the time lag.
When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag before
the shock can be felt. This is used for checking the condition of the O/D direct clutch, forward clutch,
and 1st & reverse brake.
NOTICE:
Do the test at normal operating fluid temperature 50 ± 80 °C (122 ± 176 °F).
Be sure to allow 1 minute interval between tests.
Take 3 measurements and take the average value.
(1) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(2) Fully apply the parking brake.
(3) Start the engine and check idle speed.
Idle speed : 750 ± 50 rpm (In N position and air conditioner OFF)
(4) Shift the shift lever from N to D position. Using a stop watch, measure the time from when the
lever is shifted until the shock is felt.
Time lag: N " D Less than 1.2 seconds
(5) In the same manner, measure the time lag for N " R.
Time lag: N " R Less than 1.5 seconds
Evaluation (If N " D time or N " R time lag is longer than the specified):
ProblemPossible cause
N " D time lag is longer
Line pressure too low
Forward clutch worn
O/D one±way clutch not operating
N " R time lag is longer
Line pressure too low
Direct clutch worn
1st & reverse brake worn
O/D one±way clutch not operating properly

7. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation fluid temperature 50 ± 80 °C (122 ± 176 °F).
The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
Be careful to prevent SST's hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the transaxle case front left side and connect SST.
(See page AX±17 for the location to connect SST)
SST 09992±00095 (09992±00231, 09992±00271)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake pedal and shift into D position.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when
engine speed reaches stall speed.
(9) In the same manner, do the test in R position.
Specified line pressure:
ConditionD position kPa (kgf/cm2, psi)R position kPa (kgf/cm2, psi)
Idling362 ± 422 (3.7 ± 4.3, 53 ± 61)618 ± 794 (6.3 ± 8.1, 90 ± 115)
Stall735 ± 862 (7.5 ± 8.8, 107 ± 125)1,373 ± 1,608 (14.0 ± 16.4, 199 ± 233)
If the measured pressure is not up to the specified value, recheck the throttle cable adjustment and retest.
